COLORADO SPRINGS, Colo., 20 Dec. 2016. Cobham in Colorado Springs, Colo., has received Defense Logistics Agency (DLA) Qualified Manufacturer's List (QML) V qualification of the company's UT64CAN333x series of radiation-tolerant Controller Area Network (CAN) flexible data rate (FD) CAN bus transceivers.

QML V qualification will assure customers the CAN transceivers have been through rigorous DLA testing. The CAN Transceiver series will be produced by Cobham Semiconductor Solutions in Colorado Springs, Colo., a business unit of the Cobham Advanced Electronics Solutions sector.

"The series provides the physical layer that permits operation on a differential CAN bus and are ideal for sensor monitoring, system telemetry and command and control applications," says Elaine Gonsalves, product marketing manager at Cobham.

Developed to ISO 11898-2 and 11898-5 standards, the UT64CAN333x series are capable of baud rates between 10 kilobits per second to 8 megabits per second, and include slope-control for the slew rate of the transmissions for baud rates as fast as 500 kilobits per second.

A standby mode disables the transmitter circuit to conserve power while monitoring the bus for activity. The UT64CAN333x series of transceivers can support as many as 120 nodes.

The three transceiver options are the UT64CAN3330, which provides a low-power sleep mode; the UT64CAN3331, which supports a bus-isolated diagnostic loopback; and the UT64CAN3332, which offers the ability to monitor bus traffic enabling the local controller to change its baud rate to match the operations of the bus.

Cobham's RadTolerant CAN transceivers have radiation performance of 100 krad(Si) total dose with latch up of LET < 141 Mev-cm2/mg. The UT64CAN333x series is packaged in an 8-lead ceramic flatpack. Prototypes and production parts are available now with Standard Microcircuit Drawing (SMD) number 5962-15232, QML-Q and V.
